Nurses' Tobacco-Related Knowledge, Attitudes, and Practice in Four Major Cities in China

JOURNAL OF NURSING SCHOLARSHIP, Issue 1 2007
Sophia S.C. Chan
Purpose: To (a) identify Chinese nurses' tobacco-related knowledge, attitude, and practice (KAP), including perception of competency in smoking-cessation interventions; (b) identify barriers and facilitators to smoking cessation interventions to patients; and (c) assess the learning needs and smoking status of nurses. Design: A cross-sectional survey was conducted in four major cities (Beijing, Shanghai, Guangzhou, and Chongqing) in China from November to December 2003. Methods: 2,888 registered nurses working in hospitals affiliated with five university schools of nursing in these cities were invited to complete a questionnaire. An instrument used to assess tobacco-related KAP in Hong Kong was translated into Chinese and pilot tested to ensure reliability and validity. Findings: 2,179 questionnaires were returned and after exclusion of the grossly incomplete questionnaires, 1,690 were included in the present analysis. Only 2% of participants were current and 1% were former smokers; most had not received training for smoking-cessation interventions as part of their nursing education program. Two-thirds recognized smoking as a leading cause of preventable death and that smoking cessation was the most cost effective intervention, but only a third routinely assisted patients' quit attempts. Nurses who received training reported greater competence in providing smoking-cessation intervention, and more frequent practice of cessation interventions. Conclusions: Chinese nurses had some knowledge about the health effects of tobacco use, but seldom practiced smoking-cessation interventions. Those who had prior training had greater competence and more practice. Including tobacco control, especially smoking cessation, in nursing curricula in China has the potential to save millions of lives. [source]

To the Islands , Photographs of Tropical Colonies in The Queenslander

HISTORY COMPASS (ELECTRONIC), Issue 1 2010
Hannah Perkins
Australian readers knew a great deal about the Pacific Islands in the early 20th century. This understanding came from missionary fund-raising campaigns, visiting lantern-slide lecturers, postcards and illustrated books and encyclopaedia but most of all, after the mid-1890s, from heavily illustrated weekend newspapers. These were published in all major cities and offered a regular visual window on ,the islands', of which three were Australian colonies shortly after World War I. This paper argues that Australians were well-informed about the potential for settlement, and commercial and economic opportunities. It notes that illustrated newspapers were dominated by ethnographic images of the material culture and lifestyles of island peoples, but that images of wharves, plantations, port towns and colonial infrastructure were provided for those readers who thought the western Pacific should become an Australian or at least a British sphere of interest. Ultimately The Queenslander's editorial motivation was to alert Australian readers to the economic potential of plantations, trade, mining, travel and settling in the nearby tropics. [source]

Consumer attitudes towards debt in an islamic country: managing a conflict between religious tradition and modernity?

INTERNATIONAL JOURNAL OF CONSUMER STUDIES, Issue 3 2008
Alhassan G. Abdul-MuhminArticle first published online: 10 APR 200
Abstract Saudi Arabia is an important country in the Islamic world, and Islam prohibits the payment and receipt of interest, a key component of modern commercial bank loans. Yet the levels of commercial bank lending in the country for private non-commercial purposes has been rising sharply for the past decade. This study seeks an explanation for this increase by examining the nature of consumer attitudes towards debt in the country, and whether the increasing levels of consumer debt can be explained by existing positive debt attitudes. Using data from a convenience sample of consumers in the major cities of the country, the study finds general debt attitudes to be surprisingly positive, though tempered by the consumption purpose for which the debt is acquired. However, the positive attitudes are unrelated to actual debt acquisition. Rather, socio-demographic differences in attitudes are similar to those reported in the literature. Attitudes are generally more positive among young, highly educated Saudi males than other socio-demographic groups. This suggests a possible struggle to manage a conflict between the Islamic prohibition of interest-based borrowing and demands of the modern economy. [source]

Skin color measurement in Chinese female population: analysis of 407 cases from 4 major cities of China

INTERNATIONAL JOURNAL OF DERMATOLOGY, Issue 8 2007
Liu Wei MD
Background, Color assessment of human skin is an important index both in dermatology and in cosmetology. Methods, Skin color measured in 407 Chinese women selected from four different cities in China is reported in the 1976 Commission International de L'eclairage (CIE)-color space, according to the skin color typing method proposed by Chardon et al. in 1991. The skin color of buttocks and hands, which represent sun unexposed and exposed sites, respectively, were measured with a Minolta 2500d chromameter. Individual typology angle (ITA°) of each volunteer was calculated based on the measured L* and b* values and her skin complexion was graded accordingly. Results, The results show that most of the volunteers had a "light" skin color at their unexposed sites, namely grade II (65.5%), and then grade III (intermediate, 23.1%), and I (very light, 9.6%). The skin colors at exposed sites of the studied group were mainly grade III (intermediate, 45.7%), followed by grade IV (tan, 42.0%) and II (light, 7.9%). The difference among the investigated cities, the relationship between skin color and ages, and the complexion changes from unexposed site to exposed site were analyzed based on the data from the research. Conclusion, The authors believed that the present results might basically represent the complexion conditions of Chinese women. [source]

Indigenous children and receipt of hospital dental care in Australia

INTERNATIONAL JOURNAL OF PAEDIATRIC DENTISTRY, Issue 5 2006
L. M. JAMIESON
Summary., Objective., The aim of this study was to investigate dental procedures received under hospital general anaesthetic by indigenous and non-indigenous Australian children in 2002,2003. Methods., Separation data from 1297 public and private hospitals were obtained from the Australian Institute of Health and Welfare National Hospital Morbidity Database for 2002,2003. The dependant variable was the admission rate of children receiving four categories of dental care (i.e. extraction, pulpal, restoration or other). The explanatory variables included sex, age group, indigenous status and location (i.e. major city, regional or remote). Rates were calculated using estimated resident population counts. Results., The sample included 24 874 children aged from 2 to 14 years. Some 4·3% were indigenous (n = 1062). Admission rates for indigenous and non-indigenous children were similar, with indigenous males having 1·2 times the admission rate of indigenous females (P < 0·05). Indigenous children aged < 5 years had 1·4 times the admission rate of similarly aged non-indigenous children (P < 0·001) and 5·0 times the admission rate of 10,14-year-old indigenous children (P < 0·001). Remote-living indigenous children had 1·5 times the admission rate of their counterparts in major cities or regional areas (P < 0·001), and 1·4 times the admission rate of remote-living non-indigenous children (P < 0·01). The extraction rate of indigenous males was 1·3 times that of non-indigenous males (P < 0·01), and 1·2 times that of indigenous females (P < 0·05). Pre-school indigenous children had 2·2 times the extraction rate of similarly aged non-indigenous children (P < 0·001), and 5·3 times that of indigenous 10,14-year-olds (P < 0·001). The extraction rate of remotely located indigenous children was 1·5 times that of indigenous children in major cities (P < 0·01), and 1·8 times that of remote-living non-indigenous children (P < 0·001). Conclusions., In certain strata , particularly males, the very young and those in remote locations , indigenous children experienced higher rates of extractions than non-indigenous children when undergoing care in a hospital dental general anaesthetic setting.

Consumers' product evaluation: a study of the primary evaluative criteria in the precious jewellery market in the UK

JOURNAL OF CONSUMER BEHAVIOUR, Issue 2 2001
Dr Ahmad Jamal Lecturer in Marketing
Abstract It is normally argued that consumers make their purchase decisions on the basis of their evaluation of, and knowledge about, the product attributes. This paper reports findings from a research study, which was conducted to determine the nature and type of evaluative criteria used by an individual while purchasing a piece of precious jewellery. In doing so, the study looked into the significance of product category knowledge, brand familiarity and brand consciousness in product evaluation. A questionnaire was sent to 500 consumers of precious jewellery in five major cities of the UK. Results indicate that, in general, subjective attributes are more important for people buying precious jewellery than the objective attributes. The significance of specific attributes during product evaluation could vary according to one's level of product category knowledge, brand familiarity and brand consciousness. The paper discusses implications for the marketers. Copyright © 2001 Henry Stewart Publications. [source]

"Kana sora ratswa ngaritswe": African Nationalists and Black Workers , The 1948 General Strike in Colonial Zimbabwe

JOURNAL OF HISTORICAL SOCIOLOGY, Issue 3 2000
Ian Phimister
For almost two weeks in April 1948 colonial Zimbabwe's two major cities, as well as smaller towns, mines and farms were convulsed by mass unrest. Although the causes of the General Strike have long been recognised as having their origins in the urban squalor and rampant inflation of the immediate post-war era, there is little agreement about either its organisation or its significance. Recent interventions in the debate have tended to strengthen existing prejudices. This paper advances four linked propositions which radically reformulate previous positions: that, while the development of secondary industry and the related growth of colonial Zimbabwe's urban areas were both relatively large by the modest standards of Sub-Saharan African, the scale was small in absolute terms; that these processes and their social consequences differed considerably between Bulawayo and Salisbury; that that the limited scale of these processes often meant that parochial concerns were more important than national issues; and that while all of this facilitated a greater degree of control over events in Bulawayo, if not in Salisbury, by an elite leadership than some writers have conceded, these events did not amount to a colony-wide General Strike.

Impact of Society of Hospital Medicine workshops on hospitalists' knowledge and perceptions of health care,associated infections and antimicrobial resistance,

JOURNAL OF HOSPITAL MEDICINE, Issue 4 2007
Megan E. Bush-Knapp MPH
Abstract BACKGROUND Health care,associated infections and antimicrobial resistance threaten the safety of hospitalized patients. New prevention strategies are necessary to address these problems. In response, the Society of Hospital Medicine (SHM) in collaboration with the Centers for Disease Control and Prevention developed and conducted workshops to educate hospitalists about conducting quality improvement programs to address antimicrobial resistance and health care,associated infections in hospitalized patients. METHODS SHM collected and analyzed data from pretests and posttests administered to physicians who attended SHM workshops in 2005 in 1 of 3 major cities: Denver, Colorado; Boston, Massachusetts; or Portland, Oregon. RESULTS A total of 69 SHM members attended the workshops, and 50 completed both a pretest and a posttest. Scores on the knowledge-based questions increased significantly from pretest to posttest (x, = 48% vs. 63%, P < .0001); however, perceptions of the problem of antimicrobial resistance did not change. Most participants (85%) rated the quality of the workshop as "very good" or "excellent" and rated the workshop sessions as "useful" (x, = 3.9 on a 5.0 scale). CONCLUSIONS Hospitalists who attended the SHM workshop increased their knowledge of health care,associated infections, antimicrobial resistance, and quality improvement programs related to these issues. Similar workshops should be considered in efforts to prevent health care,associated infections and antimicrobial resistance.

Nurses' Tobacco-Related Knowledge, Attitudes, and Practice in Four Major Cities in China

URBAN CLUSTERS AS GROWTH FOCI,

JOURNAL OF REGIONAL SCIENCE, Issue 2 2009
Boris A. Portnov
ABSTRACT Urban clusters are geographic concentrations of urban places, some of which may include major cities. Unlike agglomerations, whose geographic boundaries are clearly delineated, urban clusters have "variable" boundaries, with each urban settlement being part of its "own" cluster of populated places, located within its commuting range. As our study indicates, the effect of clustering on urban growth is not uniform: it appears to be positive in low density clusters, and negative in densely populated ones. In particular, outside densely populated areas, towns surrounded by other localities tend to evince higher rates of population growth than their "lone" counterparts. [source]

Secular changes in stature and body mass index for Chinese youth in sixteen major cities, 1950s,2005

AMERICAN JOURNAL OF HUMAN BIOLOGY, Issue 5 2008
Cheng-Ye Ji
Evidence shows a secular trend in physical growth in China in recent years. We analyze the secular trend of stature and body mass index (BMI) for the period 1950s,2005 to provide biological evidence for policy-makers to identify measures for improving Chinese children's health. Data come from the historical records in 1950s and the successive cycles of the Chinese National Survey on Student's Constitution and Health. Subjects were 7- to 18-year-old youth from 16 cities. Sex,age differences in mean stature and BMI values between the surveys were analyzed, and the increments per decade were compared. An overall positive secular trend was found in 1950s,2005. Mean stature of the 18-year olds increased from 166.6 to 173.4 cm for males and from 155.8 to 161.2 cm for females, yielding rates of 1.3 and 1.1 cm/decade; the overall increments of BMI values were 2.6 for males and 1.8 for females, yielding rates of 0.8 and 0.6/decade, respectively. The most significant changes occurred during puberty. The overall positive secular trend is closely associated with the socioeconomic progress and the improvement of livelihood. Strong evidence suggests that in China this trend will be continued for many years. Further studies are needed to explore how to ensure healthy changes for poorer rural youth. Effective preventive strategies and measures should be taken to prevent the progressive increase in the prevalence of childhood obesity accompanying this trend. Am. J. Hum.

The Spanish Influenza of 1918 in St. Louis, Missouri

PUBLIC HEALTH NURSING, Issue 5 2006
Irene Kalnins
ABSTRACT In view of current concern about a possible pandemic of virulent avian influenza, it is timely to revisit the public health response to the "Spanish" influenza of 1918. St. Louis, Missouri, was the most successful of nine largest cities in limiting the death toll from influenza and pneumonia through the use of public health measures during the first 8 weeks of the epidemic. A second wave of cases increased the final death rate, but it remained below that of other major cities. Public health officials attributed the lower death rate to the early and rigorous ban on public gatherings. [source]

Gentrification Trends in New Transit-Oriented Communities: Evidence from 14 Cities That Expanded and Built Rail Transit Systems

REAL ESTATE ECONOMICS, Issue 2 2007
Matthew E. Kahn
Over 25 billion dollars were spent between 1970 and 2000 in 14 major cities in the United States on the construction of new rail transit lines. This massive investment in rail transit construction and expansion allows me to study the consequences of local public goods improvements for communities nearby new stations. This article uses a 14-city census tract,level panel data set covering the years 1970 to 2000 to document significant heterogeneity in the effects of rail transit expansions across the 14 cities. Communities receiving increased access to new "Walk and Ride" stations experience greater gentrification than communities that are now close to new "Park and Ride" stations. [source]

Overseeing organizations: configuring action and its environment

THE BRITISH JOURNAL OF SOCIOLOGY, Issue 2 2002
Christian Heath
ABSTRACT Despite the widespread deployment of CCTV through most major cities and towns in great Britain, and the importance of surveillance to contemporary debates within the social sciences, there remains relatively little detailed research concerned with the practical use of these technologies in the workplace. In this paper, we examine how personnel in the operation rooms in London Underground use CCTV and related equipment to identify problems and events and to develop a co-ordinated response. In particular, we consider how personnel configure scenes to make sense of and interpret the conduct of the travelling public in organizationally relevant ways, and how they shape the ways in which both passengers and staff see and respond to each others' actions. In addressing how personnel constitute the sense and significance of CCTV images, we reflect on the development of information processing systems which are designed to automatically detect conduct and events.

Life Insurance for Living Kidney Donors: A Canadian Undercover Investigation

AMERICAN JOURNAL OF TRANSPLANTATION, Issue 7 2009
R. C. Yang
Some living kidney donors encounter difficulties obtaining life insurance, despite previous surveys of insurance companies reporting otherwise. To better understand the effect of donation on insurability, we contacted offices of life insurance companies in five major cities in Canada to obtain $100 000 of life insurance (20-year term) for 40 fictitious living kidney donors and 40 paired controls. These profiles were matched on age, gender, family history of kidney disease and presence of hypertension. The companies were blinded to data collection. The study protocol was reviewed by the Office of Research Ethics. The main study outcomes were the annual premium quoted and total time spent on the phone with the insurance agent. All donor and control profiles received a quote, with no significant difference in the premium quoted (medians $190 vs. $209, p = 0.89). More time was spent on the phone for donor compared to control profiles, but the absolute difference was small (medians 9.5 vs. 7.0 min, p = 0.046). Age, gender, family history of kidney disease and new-onset hypertension had no further effect on donor insurability in regression analysis. We found no evidence that kidney donors were disadvantaged in the first step of applying for life insurance. The effect donation has on subsequent phases of insurance underwriting remains to be studied. [source]

Population Structure in Contemporary Sweden,A Y-Chromosomal and Mitochondrial DNA Analysis

ANNALS OF HUMAN GENETICS, Issue 1 2009
T. Lappalainen
Summary A population sample representing the current Swedish population was analysed for maternally and paternally inherited markers with the aim of characterizing genetic variation and population structure. The sample set of 820 females and 883 males were extracted and amplified from Guthrie cards of all the children born in Sweden during one week in 2003. 14 Y-chromosomal and 34 mitochondrial DNA SNPs were genotyped. The haplogroup frequencies of the counties closest to Finland, Norway, Denmark and the Saami region in the north exhibited similarities to the neighbouring populations, resulting from the formation of the Swedish nation during the past millennium. Moreover, the recent immigration waves of the 20th century are visible in haplogroup frequencies, and have led to increased diversity and divergence of the major cities. Signs of genetic drift can be detected in several counties in northern as well as in southern Sweden. With the exception of the most drifted subpopulations, the population structure in Sweden appears mostly clinal. In conclusion, our study yielded valuable information of the structure of the Swedish population, and demonstrated the usefulness of biobanks as a source of population genetic research. Our sampling strategy, nonselective on the current population rather than stratified according to ancestry, is informative for capturing the contemporary variation in the increasingly panmictic populations of the world.

Self-provision in retirement: Quantitative evidence on older Australians' expectations and experiences

AUSTRALASIAN JOURNAL ON AGEING, Issue 1 2009
Rachel Ong
Objectives:,To explore factors that correlate with expectations and experiences of self-provision in retirement. Methods:,A regression modelling approach is adopted using a national survey that contains data on the retirement expectations and experiences of older Australians. Results:,Older Australians approaching retirement are more likely to expect to be self-funded in retirement if they possess high qualification levels, stable employment and have healthy levels of wealth holdings. Divorced or separated older women are more likely to expect to be welfare-reliant than other groups. The presence of children, disabilities and residence outside major cities do not affect prospective retirees' expectations of being primarily self-funded in retirement, but they do impact negatively on actual self-provision in retirement. Forced retirement will significantly decrease the probability of self-provision in retirement. Conclusions:,Policy reforms that focus on increasing employment opportunities for women after child-bearing and promoting retirement choice will reduce welfare reliance among older Australians.

The increasing cost of healthy food

AUSTRALIAN AND NEW ZEALAND JOURNAL OF PUBLIC HEALTH, Issue 2 2010
Michelle Harrison
Abstract Objective: To assess changes in the cost and availability of a standard basket of healthy food items (the Healthy Food Access Basket [HFAB]) in Queensland. Methods: Analysis of five cross-sectional surveys (1998, 2000, 2001, 2004 and 2006) describes changes over time. Eighty-nine stores in five remoteness categories were surveyed during May 2006. For the first time a sampling framework based on randomisation of towns throughout the state was applied and the survey was conducted by Queensland Treasury. Results: Compared with the costs in major cities, in 2006 the mean cost of the HFAB was $107.81 (24.2%) higher in very remote stores in Queensland, but $145.57 (32.6%) higher in stores more than 2,000 kilometres from Brisbane. Over six years the cost of the HFAB has increased by around 50% ($148.87) across Queensland and, where data was available, by more than the cost of less healthy alternatives. The Consumer Price Index for food in Brisbane increased by 32.5% over the same period. Conclusions and Implications: Australians, no matter where they live, need access to affordable, healthy food. Issues of food security in the face of rising food costs are of concern particularly in the current global economic downturn. There is an urgent need to nationally monitor, but also sustainably address the factors affecting the price of healthy foods, particularly for vulnerable groups who suffer a disproportionate burden of poor health.

Health status differentials across rural and remote Australia

AUSTRALIAN JOURNAL OF RURAL HEALTH, Issue 1 2009
Andrew Phillips
Abstract This paper describes mortality and disease patterns across five broad remoteness categories of Australia, with reference to the context in which those outcomes develop and are treated. Health and its outcomes become worse as remoteness increases. Some of this phenomenon reflects proportionally greater numbers of Aboriginal and Torres Strait Islander people in remote areas coupled with their poorer overall health outcomes; however, mortality for non-indigenous people is clearly higher outside compared with inside major cities. Migration of people seeking services likely reduces the size of interregional health disparity. Poorer health outcomes stem from worse risk factor profiles and average lower levels of income and of education, poorer physical and financial access to services, higher occupational and environmental risk, as well as factors unique to Aboriginal and Torres Strait Islander health. Little is known about the health benefits of living outside major cities. Diseases of the circulatory system and injuries account, respectively, for 40% and 18% of the excess mortality outside major cities. Death rates are declining over time in all (particularly remote) areas, but rates of death due to certain lung diseases in rural women are not, and rates of suicide have increased in remote areas. Ostensibly, prevalence of mental ill-health appears roughly similar in all remoteness areas. Dental health is poorer and disability is more prevalent outside major cities, as are a range of infectious diseases. Although pertinent, the effects on rural health of climate change and resource degradation generally have not been addressed in this paper. [source]

Bauphysikalische, ökologische und ökonomische Bewertung von geförderten Sanierungskonzepten in Wien

BAUPHYSIK, Issue 3 2009
Azra Korjenic Univ.-Ass.
Energieeinsparung; Gebäudebestand Abstract In diesem Beitrag wird die Nachhaltigkeit von Gebäudesanierungen untersucht, wobei die Reduzierung des Energieverbrauchs das oberste Ziel ist, was mit bis zu 80 % erreicht werden kann. Während in anderen Großstädten Europas das Konzept der Flächensanierung praktiziert wurde und wird, wird in Wien die "sanfte Sanierung" propagiert und auch gefördert. Die Stadt Wien hat dafür verschiedene Sanierungskonzepte bei der Hand. In dieser Untersuchung werden die verschiedenen geförderten Sanierungskonzepte anhand eines realen Beispiels gezeigt und rechnerisch überprüft. Ein Vergleich der verschiedenen Konzepte beleuchtet die einzelnen Punkte der Sanierung: Energieeffizienz, Sanierungskosten, Belastung für den Eigentümer bzw. Mieter der Wohnungen und Belastung für den Fördergeber (Land Wien). Die Ergebnisse ausgeführter Sanierungskonzepte brachten folgende Erkenntnisse bzw. Problemstellungen: , die Sanierungsmaßnahmen kommen hauptsächlich den Mietern zugute, während der Kostenträger (Eigentümer) nur die Wertsteigerung als Nutzen hat; , mangelnde Bereitschaft der Bewohner zur Sanierung; , erhebliche Mehrkosten für Passivhaustechnik; , zu geringe höchstzulässige Gesamtsanierungskosten. Evaluation of retrofitting concepts and municipal sponsoring in Vienna. Major energy efficiency improvements can be achieved via building stock retrofit. While in some major cities in Europe, mostly large-area building retrofit measures have been targeted; in Vienna a gradual thermal improvement of the building stock has been practiced. Thereby, a number of different instruments and programs have been promoted by the regional government. In the present contribution, a number of such programs are compared and evaluated based on the demonstrative case of a concrete example. Thereby, multiple related issues were addressed: energy efficiency, retrofit expenses, burden for the building owners and tenants, and burden for the funding agency (Municipal of Vienna). The results suggest: , the main beneficiary of retrofit programs are typically the tenants. The landlords benefit indirectly due to the appreciation of property value; , there is a certain lack of willingness on the side of the occupants toward thermal building retrofit measures; , achieving passive house standard in the course of retrofit measures cause significant additional costs; , permissible (fundable) maximum total retrofit expenses has been set too low.

Perspectives on probation and mandated mental health treatment in specialized and traditional probation departments,

BEHAVIORAL SCIENCES & THE LAW, Issue 4 2003
Jennifer L. Skeem Ph.D.
Despite the prevalence of mentally ill probationers, and probation officers' (POs') central role in their supervision, this is the first reported study to investigate how POs implement mandates to participate in psychiatric treatment. Five focus groups were conducted in major cities with 32 POs and 20 probationers representing a mix of traditional and "specialty" probation agencies. Three key findings resulted. First, there were considerable differences between POs in specialty and traditional agencies in the nature, range, and timing of strategies applied to monitor and enforce treatment compliance. Second, the quality of PO,probationer relationships colored POs' use of these strategies and was perceived as central to probationer outcomes. Relationships characterized by a respectful, personal, approach were perceived as more effective in achieving desired outcomes than those that were more authoritarian. Third, specialty agencies strongly emphasized offender rehabilitation whereas traditional agencies focused more exclusively on community safety. These agencies differed in how well probationers with mental illness "fit" their standard operating procedure. Implications for future research and directions for probation practice are discussed.

Monitoring of fluoroquinolone residual levels in chicken eggs by microbiological assay and confirmation by liquid chromatography

BIOMEDICAL CHROMATOGRAPHY, Issue 1 2008
Hee-Jung Cho
Abstract The primary objective of this study was to develop a simple, rapid, and efficient method for the simultaneous determination of four fluoroquinolone residues, ciprofloxacin (CFX), danofloxacin (DFX), enrofloxacin (EFX) and norfloxacin (NFX), in chicken eggs. The samples were first monitored by microbiological assay using Escherichia coli as the reference organism, and were then quantified using HPLC with a fluorescence detector. Egg samples were extracted by the liquid-phase extraction process, and the analytes were analyzed via an ODS column using a mixture of acetonitrile and 0.4% phosphoric acid,0.4% triethylamine (15: 85, v/v) as a mobile phase (pH = 2) without purification. The calibration curves were linear (r2 , 0.999) over a concentration range of 0.1,1.0 µg/mL. The majority of the mean recoveries at four different fortification levels, 0.1, 0.2, 0.5 and 1.0 ppm, ranged from 73.7 ± 7.2% to 87.1 ± 12.7%, and the repeatability (as the relative standard deviation) from three repetitive determinations of recovery was between 1.03 and 18.83%. The calculated limit of quantitation (LOQ) was 9 ppb for CFX, EFX and NFX and 0.6 ppb for DFX. Both the bioassay and HPLC methods were applied to 120 total egg samples collected from the six major cities in the Republic of Korea. The bioassay, showed that two samples were positive (i.e contained inhibiting substances). On the other hand, the results of HPLC only identified and quantified the residues of enrofloxacin (from 0.43 to 1.02 ppm) in three samples out of 120. We concluded that the bioassay can be used as a routine screening method for the presence of fluoroquinolones in chicken eggs, which can be confirmed and quantified using LC.

Disciplining Society through the City: The Genesis of City Planning in Brazil and Argentina (1894,1945)

BULLETIN OF LATIN AMERICAN RESEARCH, Issue 2 2003
Joel Outtes
This paper looks at the genesis of a discourse on urbanismo (city planning) in Brazil and Argentina between 1894 and 1945 using the ideas of Michel Foucault on discipline and his concept of bio,power. The demographic pattern of the major cities in both countries from 1890 onwards and the renewals of the centres of these cities are also discussed. Other sections are dedicated to the plans proposed for the same cities in the 1920s and to urban representations, such as ideas about social reform, the role of hygiene as a point of departure for planning, and the relationship of ideas on Taylorism (scientific management) and the city. The paper also discusses the planners opposition to elections, when they claimed that they were the only ones qualified to deal with urban problems and therefore they should be employed in the state apparatus. Other concerns of the paper are the use of planning as an element of nation building and ideas defining eugenics (race ,betterment') as an important aspect of city planning. I conclude by arguing that, if implemented, city planning was a way of creating an industrial culture, disciplining society through the city, although the industrial proletariat has never made up the majority of the population in Brazil or Argentina. Even if many aspects of the plans proposed for both countries were not implemented, the discourse of planners can be seen as a will to discipline society through the city. This discipline would affect the freedom of movement of human bodies, and is therefore approached through Foucault's concepts of bio,power and discipline [source]

Effects of urbanization on the land sea breeze circulation over the Pearl River Delta region in winter

INTERNATIONAL JOURNAL OF CLIMATOLOGY, Issue 7 2010
Xi Lu
Abstract In this study, the fifth-generation Pennsylvania State University-National Center for Atmospheric Research Model (MM5) was used to investigate the effects of urbanization on land,sea breezes (LSBs) in the Pearl River Delta (PRD) region, which is a rapidly developing area located in southern China. LSBs in the 2003/2004 winter were simulated utilizing an approach in which the NCEP Final Analysis data averaged in the 2003/2004 winter is used as initial and lateral boundary conditions for the model. The simulated surface winds are shown to be capable of reproducing the basic features and diurnal variation of the LSBs. Sensitivity experiments with changes in land uses were performed with this model. Results of these experiments show that urbanization in the PRD region can have significant effects on the patterns of the LSBs and circulation in the region. In particular, it has been shown that the urbanization of Shenzhen (a major city located in the eastern coast of the PRD and neighbouring to the north of Hong Kong) may significantly enhance the sea breeze to the west of Hong Kong in the early afternoon. This may enhance the low-level convergence in Hong Kong and may worsen the air pollution problem there. On the other hand, the effects of urbanization in the western coast of the PRD region are relatively local and LSBs on the eastern PRD are generally not affected.
